Synthesis & characterization of Zn3 (VO4)2 pigment for anti-corrosive coating application

Abstract

This study has reported a simple and cost-effective method for the synthesis of the corrosion inhibitor zinc vanadate nano-pigment. Further, the prepared pigment has been well characterized by different techniques such as XRD, FESEM, FTIR, EIS, etc. The formation of zinc vanadate nanoparticles has been confirmed by the FESEM. Zinc vanadate nano-pigment-based anti-corrosive coating has been prepared in epoxy resin and has been compared with zinc phosphatebased epoxy coating for the anticorrosive properties using an electrochemical impedance test (EIS test). The result has indicated that zinc vanadate nano-pigments have exhibited better performance in coating applications and also have shown high inhibitor efficiency and a lower corrosion rate. Thus, it has found potential scope in anticorrosive coating applications.
